String Theory is one of the revolutionary and most controversial concepts in physics that aims to unify all of the particles and fundamental forces of nature into one single theory. 🌌 engineering
,"In the early 1980s, theorists realized that the Standard Model itself could be made supersymmetric and that this extension would resolve some vexing problems with the theory. For example, the small mass of the Higgs boson is—its calculation requires subtracting two very large numbers that just happen to be slightly different from each other."
"We are used to living in four dimensions. If you are arranging a meeting then you need to give one more piece of information: the time of the meeting, say 3 pm. With four coordinates you can describe any event. We don't tend to clump time with the spatial dimensions but if you think about it, any event really happens in a spacetime with four dimensions.
theory was developed in the 1970s. This was an attempt to unify all the fundamental forces except gravitation - ultimately unifying the weak nuclear interactions with electromagnetism.Other theories then started taking shape... Like,Superstring Theory, or supersymmetric string theory, is what you get when string theory and the concept of supersymmetry combine. If you're not familiar with supersymmetry, gather round..
It does this with a new particle, the Higgs boson. While the Standard Model seems to predict that all particles should be massless, this is at odds with experimental observations. The Higgs boson provides this mass. At the same time,"the extra particles predicted by supersymmetry would cancel out the contributions to the Higgs mass from their Standard-Model partners ...The new particles would interact through the same forces as Standard-Model particles, but they would have different masses.
String Theory supports 10 dimensions, 3 of which extend indefinitely and are observable to us. So, where are the other 6 spatial dimensions?The extra-dimensions are inherent in the mathematical notion ofThe surface of the sphere will look flat to the ant. So, we have a ‘local’ shape and a ‘global’ shape here. The sphere, in this case, is an example of a 2-dimensional manifold.We live in a 3-dimensional manifold.
